Answer:
a) 21,952
b) 3,375
c) 36
Step-by-step explanation:
a) 7 X 7 X 7 X 4 X 4 X 4
= 7cube X 4cube
= 343 X 64
= 21,952
b) 5 X 3 X 5 X 3 X 5 X 3( group it)
5 X 5 X 5 X 3 X 3 X 3
= 5cube X 3cube
= 125 X 27
= 3,375
c) 3 X 3 X 2 X 2
= 3square X 2square
= 9 X 4
= 36
Answer:

Step-by-step explanation:
Given


Required
Determine the rate of change.
From the given parameters, we understand that the on a daily basis, there's a charge of $0.05.
This charge represent the rates at which the fee changes on a daily basis.
Hence:

Bc would equal 26. Since ab and bc would equal the same thing, you would add (3x-1) to (3x-1) and equal it to (8x-20) and solve.
Answer:
well, okay. its basically what you wrote. assuming there was missing information.
let's dive right into it.
we'll assume that the problem asks for integers, whole numbers.
if x would be 0,
we would get 9 numbers out, 0, -1, -2, -3, -4, -5, -6, -7 and -8
if x would one, the range would be from 7 to -8, giving us 16 numbers
if x would be 2, the range would be from 14 to -8, giving us 23 numbers (7 more each time we increasex by one)
so the answer isn't a fixed value, but a function.
7x+9
the plus nine is true when x=0 and is still relevant for every other scenario
